Agenesis of the internal carotid artery (ICA) is a rare congenital anomaly. Recently, several cases of ICA agenesis have been associated with cerebral aneurysms. We present the seventh case of ICA agenesis with transcavernous anastomosis associated with cerebral aneurysms. A 47-year-old man presented with transient numbness of his left hand. Magnetic resonance angiography indicated the presence of anterior communicating artery (ACoA) aneurysms. Digital subtraction angiography revealed two ACoA aneurysms, absence of the left ICA, and an anomalous collateral vessel connecting the cavernous portions of both internal carotid arteries, which was considered to be a transcavernous anastomosis...

We report two cases of "pure intra-optic-canal schwannoma." The first patient was a 67-year-old female who presented with a visual field defect and visual impairment in the right eye, and the second patient was a 17-year-old female with progressive visual impairment. Both patients underwent tumor resection through frontotemporal craniotomy combined with extradural anterior clinoidectomy and unroofing of the optic canal. The tumors were not attached to the optic nerve (ON) and were located exclusively inside the optic canal...

Cranioplasty is a comparatively simple neurosurgical procedure, and fatal complications are rare. This report describes two cases of critical brain swelling after otherwise uneventful cranioplasty. Both cases had subarachnoid hemorrhage and extremely similar clinical courses. They underwent decompressive craniotomy and clipping in the acute phase and had cranioplasty in the chronic phase, resulting in serious cerebral swelling and death. Deep venous sinus thrombosis was revealed in the autopsy for one case...

Endoscopic endonasal transorbital approach has been described for the removal of orbital lesions located anteromedially in temporal fossa. The same has been observed to be a versatile approach to the anterior and middle cranial fossa only in laboratory studies. This is the first clinical report of combined transorbital transnasal endoscopic approach to the cavernous sinus, superior orbital fissure, and middle cranial fossa in a case of recurrent nasopharyngeal angiofibroma using the three-surgeon six-handed technique...

Primary tumors of the brachial plexus are a rare cause of an axillary swelling. Schwannomas are benign tumors arising from Schwann cells. Most of the schwannomas occur in the head and neck region and in the flexor aspect of the limbs. We present a case of a 60-year-old female who presented with pain in the left axilla radiating to the left upper limb since 2 years and a painful swelling in her left axilla for 3 months. The diagnosis is made by fine needle aspiration cytology and magnetic resonance imaging, and confirmed by histopathological examination as schwannoma...

Intraoperative adenosine is used to induce asystole to facilitate clip ligation of intracranial aneurysms. Typically, 5-10 mg doses are used per administration and approximately 30 mg is used for a given case. An obvious concern with using adenosine is that the patient can remain in asystole or that prolonged hypotension can result in cerebral or cardiovascular ischemia. The upper limit of adenosine administration remains unclear. We present a case of a patient with a large anterior communicating artery aneurysm requiring large doses of adenosine, far exceeding previously reported cases...

We report a case of giant cell glioblastoma (GCG) in a 13-year-old child with clinical features and family history of neurofibromatosis type 1 (NF1). To the best of our knowledge, only two cases of GCG have been reported in a scenario of NF1, and only one of that was in a pediatric age group. A report on our case is presented here along with a review of literature.

Disseminated tuberculomas in the brain and spinal cord are rare. To the best of our knowledge, only nine cases of spinal intra-medullary tuberculomas with cranial involvement have been reported till date. However, involvement of all levels in the spinal cord, brain stem with pan lobar involvement of the cerebrum and cerebellum has not been reported so far. We present such a case of a 12-year-old boy with history of pulmonary tuberculosis, who presented with gradual onset of quadriparesis and generalized seizures...

A 16-year-old male presented at Bangur Institute of Neurosciences Neurosurgery Outpatient Department with history of gradually progressive paraparesis for 5 months associated with stiffness, urinary hesitancy, and urge incontinence for last 2 months. Magnetic resonance imaging spine was done which showed cystic intradural extramedullary space occupying lesion at D4/D5 to D9. Patient had 2 episodes of generalized tonic-clonic seizure on the day 4. Computed tomography scan showed pneumocephalus. Histopathological examination report was that of nonspecific inflammatory cyst...

Sixth nerve palsy is frequently due to infectious orbital lesions, trauma, elevated intracranial pressure, brainstem lesions, and vasculopathies. Here, we describe a rare cause of sixth cranial nerve (CN) palsy secondary to calvarial and orbital metastasis of prostate carcinoma. The diagnosis of the prostate carcinoma with sixth CN palsy is a very rare condition. A 66-year-old male patient presented with complaints of blurred vision, double vision, and inability to move outward in the right eye for 3 weeks...

Primary orbital lymphoma is a rare entity with only 1% of extranodal lymphomas. They usually present to ophthalmologist and surgical reserved for biopsy or tissue diagnosis. We present a patient who was referred to neurosurgery for a rapid growing orbital lymphoma. It grows from a small nodule in the eyelid to a huge, aggressive, disfiguring lesion invading bone and dura with intracranial extension within 3 months. The patient was treated with total surgical excision followed by systemic chemotherapy.

Rotational vertebral artery occlusion (RVAO) is a well-documented surgically amenable cause of vertebrobasilar insufficiency. Traditionally, patients have been imaged using dynamic rotational angiography. We report a case of RVAO in which intraoperative indocyanine green angiography (ICGA) was used to confirm adequate surgical decompression of the VA. A 57-year-old female who presented with multiple episodes of syncope provoked by turning her head to the right. Rotational dynamic angiography revealed a dominant right VA that became occluded at the level of C5/6 with head rotation to the right...

Mucoceles are chronic, expanding, mucosa lined pathology of the paranasal sinuses. Frontal mucocele usually presents with the visual complaints such as diplopia, diminution of vision, visual field defect, ptosis, orbital swelling, retro-orbital pain, displacement of eye globe, and proptosis. Very rarely, it can be present as a subcutaneous swelling. This article presents a 58-year-old male patient presenting with an asymptomatic periorbital swelling and a painless forehead mass of 3 years duration. There was a partial ptosis, and an elongated, soft, subcutaneous mass over the forehead...

Giant "true" posterior communicating artery (PCOM) aneurysms are rare and the best surgical treatment for them is unclear. We present a case of 85-year-old woman with this type of lesion, 35 mm in diameter, successfully treated by trapping and thrombectomy via pterional approach without complications. There were no perforating arteries originating from the aneurysmal wall. The patient had an uneventful postoperative course. The key for successful treatment for such lesions is preservation of perforators, as trapping may result in ischemic complications...

Extradural hematoma (EDH) generally occurs in the site of impact, that is, coup injury site. EDH is associated with fracture of skull in many a times due to direct impact. However, EDH in counter coup site is a rare occurrence. Hardly, yet, 12 cases have been reported including this case. Here, we reported a case of a 22-year-old male of contrecoup acute EDH who had sustained head injury due to fall from bike. Physical examination revealed direct impact at the left occipito-parietal region with laceration of scalp and bruise with transient loss of consciousness at the time of injury...

Subependymal giant cell astrocytomas (SEGAs) are histologically benign tumors most frequently associated with tuberous sclerosis complex (TSC). Despite their benign histopathological appearance, they may cause unfavorable outcomes due to their intraventricular location. Rarely, SEGA may be associated with hyperproteinorrhachia (high levels of proteins in the cerebrospinal fluid [CSF]), which causes malresorptive, communicating hydrocephalus; certainly, this scenario makes shunt obstruction likely in this patient population...

The common heart diseases resulting in a brain abscess are associated with a right to left shunt and include tetralogy of Fallot and transposition of great vessels. Atrial septal defect (ASD) is almost always associated with the left to right shunt and therefore is not a commonly considered risk factor for brain abscess. We report the case of a 29-year-old male, with no symptoms of cardiac disease, who presented with the left posterior frontal pyogenic abscess which led to the detection of a silent ASD. Our case emphasizes the need for a careful evaluation of the source of infection in patients with a brain abscess...
